摘要
三维相干分析技术是近几年发展起来的一项三维地震解释新技术 ,不仅解决了常规地震解释周期长、难度大等问题 ,而且能更准确地确定断层的平面展布及其它构造细节。文中介绍了三维相干分析的数学原理 ,并结合在埕岛油田中的实际应用 ,运用正反演相结合的方法 ,定性分析了低相似性与地质特征之间的对应关系。
The coherence cube is a new 3D seismic interpretation technology developed in recent year.It can reduce the period and the difficulties of normal seismic interpretation ways.At the same time,it can effectively determine the spatial distribution of faults and other detail features.This paper introduces the mathematical basis and method of 3D coherence technology firstly,and then together with real data of Chengdao oilfield and inverse theory qualitatively analyzes the correlation relationship between low coherence and geological features.
